Eyes on Asteroids.

Track over 30,000 asteroids that are near Earth's orbit, see the next 5 closest approaches to Earth, and learn about current and historic NASA asteroid and comet missions in this real-time 3D simulation of the solar system. Try out the interactive "scrolly-telling" that lets you learn about how we define a close approach or how we determine if an asteroid or comet is categorized as a "Potentially Hazardous Object." Or ride along with NASA missions as we make historical discoveries about asteroids and comets, such as the first time we landed on an asteroid, or impacted a comet. See the DART mission impact with a binary asteroid system, and much more.
